Abstract

The present invention overcomes many of the problems associated with electromagnetic exposure of planar materials. A diagonal slot compensates for the effects of signal attenuation along the propagation path. Adjustably variable path lengths allow peaks and valleys of the electromagnetic field in one exposure segment to compensate for peaks and valleys in another exposure segment. Dielectric slabs may be used to extend the peak field region between top and bottom conducting surfaces to allow for more uniform exposure of planar materials that have a significant thickness. Specialized choke flanges prevent the escape of electromagnetic energy. One or more rollers between exposure segments may be enclosed by an outer surface to prevent the escape of electromagnetic energy.
